You're welcome, and I know what you mean...I've used the ProTank on an eGo battery too. I haven't yet seen the ProTank Mini out in the wild yet, though. You might have a wait on your hands...Thank you, Stoneface! The only reason I think I need to take the cap off and let Solar Flare 'breath' is just a teeny, tiny, perfumey thing - not enough to fuss over. And I think I will either buy another Protank for Cinnamon Roll, just to be on the safe side, or maybe those 'baby protanks' will show up in the next ten minutes or so. I reallly want some of those - this Protank looks kinda goofy on my ego-stick batteries. Well, very goofy actually!![]()
